An object of the present invention is to provide a suction cleaner including a cleaner bag which is so constructed and mounted on the cleaner that one side of the bag may be folded 'downwardly while the bag remains supported from the cleaner by means oi the other side thereof, thus providing anopening in the side of the bag of considerable dimensions to allow easy removal and insertion o f the destrucible porous paper dust receptacle.

Another object of this inventionLis to providev a suction cleaner including a cleaner bag, together with novel means for supporting the bag from the cleaner for quick and easy removal.

A further object is to provide such a cleaner and bas assembly in which the detachable supporting connection between the bag andcleaner is such as to allow either-the entire removal oithe bag from the cleaner detachment ot one side for providing a sideA opening in the bag as hereinbefore mentioned;

A'further object of this invention 'iste provide a suction cleaner including 'a fan and a removable handle provided with a nipple for detachable connection with the fan case, laid nipple serving also as one portion'of tlm means for supporting the bas.

Another object is to provide aysuction cleaner including a switch casing, and a bag supporting member associated with said switch casing. 4

More specifically, it is our object to provide, in a suction cleaner having a switch casing depending below the handle thereof, a latch element slidably mounted on the -switch casing and adapted to receive a projecting elementen the bag.

A further object ato provide a novel has structure for enclosing a paper dust collecting receptacle, including a pair of side walls having upper portions which are detached from each other both at the upper edges and the ends, and a.

flap extending between the side walls from the 5 upper edge of one of them.

With these and other objects in view our invention consists in the combination construction and arrangement of the various parts-thereof, whereby the objects contemplated are at` 10 tained, as more fully set forth in the accompanying specifications, pointed out in our claims, and illustrated in the accompanying drawing, in which:

In the accompanying drawing, referring speciflcally lto Fig. 1, we have used the reference character Il to indicate the motor of the specific 40 type of suction cleaner with which this invention deals.` 'I'he motor I0 is surmounted by the fan casing Il, with one end of which the door tool I2 communicates and the other end of which is provided with a neck il to receive the nipple I4 45 of the `hollow suction handle I5. The nipple i4, is shown in section in Fig. 2-,and

comprises the sleeve portion 'ii which is pressed on the end of the hollow fibre handle i5 and the reduced end i1, which is received within the neck 50 I3 and clamped by means of a set screw i8, coacung with the em la denmng a. slot 1n the s pm; side of the neck i3.

The nipple I4 is provided with a pair of lugs 20 which are spaced apart as shown in Fig. 3 to 55 42 of which may be engaged operator.

ends of which abut against the flat face 22 of the fan casing discharge neck 23, thus preventing rotation of the handle relative to 4the fan casing. Y

The slot 2i,-closed by the face 22, of the discharge neck 23, forms an opening through which the motor cord 24 is passed. The cord is thus securely held againstV sagging, and can only be releasedvby removing the handle from the fan casing.

The switch casing 25, includes a ring 23, by means of which it is mounted upon the handle l5, and current is carried to the 'switch within the casing 25 by means of an extension cord 2l. From the switch the current is delivered through a plug and socket'connection 23 to the motor cord 24.

The conning bag is formed of a sheet of fabric bent back upon itself Yto form the side walls 29, the upper edges of which are looped and sewed to provide they sleeves through which are extended the supporting rods v3l.

The bag securing clips 32, shown in Fig. 8, en gage between them and the end portions of the rods 3l the material oi the sleeves 30. The clips are provi-ded with .end walls 33 apertured as at Y 34 to receive the threaded shanks 35 of studs 36, Y

` all that isV necessary in order to remove the bag which serve as means for attachment of the bag supporting devices which will n'ow be described.

The lugs 26 of the nipple i4 are provided with recesses 3i' to receivethe studs 36 on the lower ends oi the bag supporting rods 3l.

The studs 35 on the upper ends of the bag supporting rods are secured by slidable latch devices 33.

These latch devices are Ypreferably formed of strip metal, each being bent upwardly at one end to provide the keeper 39 apertured as at 4li- (Fig. 5) to receive the stud 35.

. The rear end oi' each latch device is bent downwardly as at 4l toprovide a trigger, the` portion by the nger of the The latch device 38 is slidably mounted against the' lower face of the switch casing25, and is I held in position by a cap 43 the end walls 44 The central portions of the end walls 44 ofthe .A

cap 43, deiined between the slots 45, are extended upwardly beyond the level of the edges of the side walls 48 to provide the projecting portions 5i! which are received inv notches 5l formed in the end caps 52 and 53 respectively of the switch casing. These end caps thus serve the double purpose of supporting the rubber strain relief member 54 oi the extension cord 21 and the insulating core members 55 of the plug connection 28, and also of securing the cap against rotation. A Y

A teat 56 is struck from the intermediate region of each latch shaft 38 and a teat 51 is struck upwardly from the bottom wall ofthe cap 43. The end loops of a coil Vspring 58 are received over the teats 56 andY 51 respectively, the teats extending sufficiently across the space within the cap 43 to prevent the spring becom- Explaining now the operation' of. the invention, it will readily be seen'how the springV 58,

-provide between them a slot 2l, and the lower exerting a pull against the latch device 38, will yieldingly urge the keeper 39 against the shoulder S0 of the stud 36. The rod l3l will thus be held under compression, which will secure the stud 36 at the lower end of the rod in its recess 31. I

Attention is directed particularly to the arrangement of the latch member 38 so that por- -tions thereof extend behind the switch casing and latch cap assembly at both ends. During the development of the present invention, the trigger 4i at one time was allowed to normally` rest in contact with the end wall of the cap 43. It was discovered that in some cases thebre handle I5 would elongate under certain conditions of moisture or other weather conditions, sufciently to hold the keeper out of engagement with the bag rod stud, or to hold it at a suiiicient distance so that the bag rod would not be securely supported.

In the present construction, the llatch device may be said to have a floating mounting, Wherein it may adjust vitself to any irregularitiesv in the normal distance between the switch casing is to grasp the trigger-4i, pull it rearwardly and allow the bag rod to drop to the position shown in Fig. l. The lower stud may then quickly be disengaged by grasping the hanging wall ci the bag and pulling upwardly slightly in a direction parallel to the handle.

The bag is provided with a iiap Bl secured near the upper edge of one side wall 29 and extending downwardly between the two sidewalls (Fig.- 4). The paper receptacle 62 is received behind the flap 5i, i. e., between said ap and the side wall to which the ap is secured. When the bag is inilated by air fromthe fan of the cleaner, the iiap 6i will befrictionally engaged between the wall ofthe receptacle and the wall of the bag, and will support the receptacle across.

the'spacebetween the bag rods 3i. It may be noted in this connection that the bag rods are disposed with a substantial space between them.

The side Walls 29 ofthe bag'are secured together from the lower corners indicated at A to points somewhat above the center of the bag as indicated at B, and from there to the upper corners of 'the bag, .are entirely detached as clearly Ashown in Figs. l and 4. Reinforcing tapes 63 are secured to the unattached edges of the side walls, each tape extending from the corner of one side wall to the corresponding corner of the opposite wall. Y

The rods 3i support the upper edges of the bag against spreading under the pressure of air 'delivered from the fan, and thus it is unnecessary to provide any means of connection between the upper edges of the bag.

It is found that the structurewherein theupper portion of one side wall of the bag may be folded downwardly while the bag remains suspended from the other wall adds greatly to the convenience and utility of a cleaner of this type, since the paper receptacle may be very easily attached and detached with very little likelihood of tearing the same while connection is being made to the discharge neck 23. In this connection it may be stated that it was formerlyY considered preferable to remove the bag entirely vfrom the cleaner -when changing paper receptacles. The receptacle would ilrst be enclosed within the bag and then the connection made between the receiving neck of the receptacle 'and the discharge neck of the fan casing.

i It is now found that the likelihood of tearing I the paper is greatly diminished by attaching the receptacle while the bag remains suspended from the cleaner handle and the present invention wherein means are provided allowing the opening of the bag while it remains suspended, not only adds greatly to the convenience by eliminating the necessity of removing the bag entirely, but also reduces the likelihood of injury to the receptacle.

We claim as our invention:
